1 '0 all'whom it may concern:

Beit known that I, fLLBERT A. Honenms, a citizen of the United. States, residing at l-ll Bronx avenue, Bridgeport, county of Fairfield, State of Connecticut, have invented an. Improvement in Shuttle-Motion for Two-Bank Looms, of which the following is I a specification. r

'ihis invention relates to the shuttle moe tionof narrow ware or narrow fabric looms. Looms of this character weaveaseries of narrow fabrics'side by side, such fabrics, if desired, having different characters or colors of filling or weft, a plurality ofseries or banks of shuttles being employed to pro-- duce this result, each series or bank carrying filler or weft threads having the. desired rharacteristics and being brought into play. as dictated by the pattern of the fabric be ing woven, or a plurality of fabrics may be woven in vertical relation. Shuttles of each series or bank are moved across the warp space of their respective fabric to lay the filling or weft, and various means have been devised to impart the desired movement t the shuttles. v

The object of the present invention is to simplify the shuttle motion as applied solely to two ban is of shuttles. By so limiting my machine a more effective and positive movement of the shuttles is given, therebyv al lowing increase of speed in the shuttlemotion, and the use of numerous parts and devices for obtaining the same end, which are incorporated in more complicated and less limited devices for operating a plurality of banks where only two banks of shuttles are necessary, is avoided, the simple shuttle mo tion mechanism of the present invention requiring considerably less space than the more complicated mechanlsm heretofore used, thus making provlslon for a greater number of shuttles and -warp spaces than could heretofore be arranged on frames .of the same length. i

With the above and other objects infview the invention com rises the construction, arrangement and operation of partsas now to be described and hereinafter specifically l and an upwardly extendingpin 40,:each located at the position shown in Fig. 4. The

claimed.

In the drawings forming a specification,

Figure I is a fragmentary front elevation of one end of the loom showing the lay of" the batten and its associated elements;

7 part of this Fig. 2 a fragmentary side elevation looking from the right of Fig. l; V I

Fig. 3 a detail end elevationof the batten andcertain of its associated elements; andv Fig. t is a fragmentary perspective view. of one end of the batten and certain of its associatedelements, parts being broken away 51 better show the structure.

The frame l0.may be of any'usual construction suitable for supporting the oper ative parts, and the battenbeam 11 located on the frame, carries a bracket 12 having parallel upstandingarms 13 and 14. in upstanding arm 13 is journaled a shaft 15 having finedonits outer end duplicate grooved pulleys l6, and fastened to the'gro'oved pulleys are straps 17 and 18,-strap l7 going over its pulley from rightto left and strap 18 over its pulley from left to right, as shown in 1, each for three quarters'of the circumference, more or less, of its pulley. )n (he loom frame is arranged a revolnblespindle. carrying parallel cranks 19 which are connected by a stud 20. After leading over leose pulleys 21 and 22 arranged-on brackets secured to the floor, the straps are attached to studs 23 and 20V carried by the up per and lower: ends, respectively, of the portions '29 and 30'which slidingly engage" arm l3, as clearly indicated at-3l and 32, re-

spectively, and inner parallel portions 33' lel'p'ortions 33 and 34 is provided with a rack pin 38, the rack pins, as shown, being atopposite ends thereof. .Arm. 14;: is provided with a downwardly extending pin 39 purpose of pins39- an'd40 will be hereinafter p explained; W hilel have shown and described SllflGS of a particular configuration,

it will be apparent that the'slides may be made in any suitable form and that the rack plus may be situated 1n any suitable locarail of the shuttle frame 43. The upper and lower shuttle rails are each provided with a shuttle rack, and to one end of each rack is secured a sliding shuttle rack plate, indicated at 414: and 45, respectively, and each of the racks carries teeth which have engagement with small pinions in the shuttle races which actuate the shuttles. Each of the sliding shuttle rack plates is provided with openings 46 properly positioned for the entrance of pins 38, respectively, and openings 47 properly positioned for the entrance of pins 39 and 40, respectively. The shuttles 48 are vertically arranged in banks, any number to a bank, and are guided in shuttle races formed by members 49 and 50. Spaces A between the banks are each ample for the passage of the warp, the raising of the shed, and the throwim of the shuttle through the shed.

Connector 51 passes through the batten beam and has pivotal engagement at its upper end with a bracket secured to the base of the lower shuttle rail. At its lower end it has pivotal connection with a lever 52 as indicated at 53.

l/Vith each revolution of the shaft carrying the parallel cranks with the studs there on, the straps 17 and 18 will in turn effect right and left rotary motions on grooved pulleys 16. and hence on gear wheel. 37, one

strap pulling and the other giving, and vice versa. As will be apparent,the reverse turns of the gear wheel will impart opposite movements to the slides and cause them to slide back and forth in parallel planes for fixed distances along the upstanding arms.

The lever has a reciprocatory movement imparted to it by mechanism on the frame, and is arranged to hold the shuttle frame in each of its extreme upward and downward positions during one complete revolution of the shaft carrying the parallel cranks. When the shuttle frame is reciprocated to its downward position, upper rack pin 38 willenter its openinglG in the upper shuttle rack plate, and pin 40 will enter its opening 47 in the lower shuttle rack plate. A complete revolution of the parallel cranks will carry each of the slides one complete trip, back and forth. The upper shuttle rack, by reason of the engagementof upper rack pin 38 with the upper shuttle rack plate, will throw the shuttles of the upper bank across their warp. spaces and back. The lower shuttle rack plate, being engaged by pin 40, which is stationary,'will remain at. rest.' lVhen nowthe sliuttleframe is reciprocated to its upward position, upper rack pin 38 will be removed from engage' ment with the upper shuttle rack plate, lower rack pin 38 will enter its opening 46 in'the lower shuttle rack plate, pin 40 will be removed from the lower shuttle rack plate, and pin 39 will enter its opening 47 in the upper shuttle rack plate. A complete revolution of the cranks will now, in a similar manner, actuate the shuttles of the lower bank across and back, and the upper rack will remain stationary. It will of course be understood that when the shuttle frame is in its downward position, lower rack 'pin 38 and pin 39 will be disengaged from their openings.
